f2fs: fix a mount fail for wrong next_scan_nid (2017-05-03 19:00:30 -0700)
----------------------------------------------------------------
for-f2fs-4.12
In this round, we've focused on enhancing performance with regards to block
allocation, GC, and discard/in-place-update IO controls. There are a bunch
of clean-ups as well as minor bug fixes.
= Enhancement
- disable heap-based allocation by default
- issue small-sized discard commands by default
- change the policy of data hotness for logging
- distinguish IOs in terms of size and wbc type
- start SSR earlier to avoid foreground GC
- enhance data structures managing discard commands
- enhance in-place update flow
- add some more fault injection routines
- secure one more xattr entry
= Bug fix
- calculate victim cost for GC correctly
- remain correct victim segment number for GC
- race condition in nid allocator and initializer
- stale pointer produced by atomic_writes
- fix missing REQ_SYNC for flush commands
- handle missing errors in more corner cases
